All modern CPUs have BIST (built-in self tests) that run even before the BIOS starts, and it would be really rare to actually have a "working" system with a faulty CPU. Errors in mprime usually indicate some other problem, such as bad memory, bad BIOS settings, overheating or an incompatibility of CPU/motherboard etc. Going back to what you said previously, you got an Nvidia 5200 graphics card? Were these ever produced for PCI express or are you using a) a normal PCI one or b)You got one of these weird mobos that have both AGP and PCI express? As I understand there are no AGP-only motherboards for core2duo. Another thought: Sometimes the CPU cooler is not entirely seated, resulting in bad thermal contact of the heatsink/CPU assembly. This is not unusual in the 775 socket since the mechanism requires quite some pressure to lock and some people are afraid to apply it ;)
